# Installation

## Binary wheel install

PyNaCl ships as a binary wheel on macOS, Windows and Linux `manylinux1` [1] , so all dependencies are included. Make sure you have an up-to-date pip and run:

    $ pip install pynacl

## Faster wheel build

You can define the environment variable `LIBSODIUM_MAKE_ARGS` to pass arguments to `make` and enable parallelization:

    $ LIBSODIUM_MAKE_ARGS=-j4 pip install pynacl

## Linux source build

PyNaCl relies on libsodium, a portable C library. A copy is bundled with PyNaCl so to install you can run:

    $ pip install pynacl

If you’d prefer to use the version of `libsodium` provided by your distribution, you can disable the bundled copy during install by running:

    $ SODIUM_INSTALL=system pip install pynacl

Warning

Usage of the legacy `easy_install` command provided by setuptools is generally discouraged, and is completely unsupported in PyNaCl’s case.

[1]

manylinux1 wheels are built on a baseline linux environment based on Centos 5.11 and should work on most x86 and x86_64 glibc based linux environments.

GNU Make (gmake) may be required for newer versions of PyNaCl. You can set the binary to use by setting the `MAKE` environment variable:

    $ MAKE=gmake pip install pynacl
